Building Interdisciplinary Learning Partnerships

Capital University Law School & Grant Medical Center partnered to provide training on medical malpractice to law students and medical residents. The course utilized a unique, interdisciplinary approach to skills training & professional development. The course attempts to meet several needs: (1) Increase experiential learning opportunities to develop professional skills and judgment; (2) Provide authentic, experiential learning that is cost-effective and accessible to all law students, including non-traditional and part­time students; and (3) Promote interdisciplinary education.https://fuse.franklin.edu/ss2016/1066/thumbnail.jp

Expanding the clinical phenotype in patients with disease causing variants associated with atypical Usher syndrome

Atypical Usher syndrome (USH) is poorly defined with a broad clinical spectrum. Here, we characterize the clinical phenotype of disease caused by variants in CEP78, CEP250, ARSG, and ABHD12. Chart review evaluating demographic, clinical, imaging, and genetic findings of 19 patients from 18 families with a clinical diagnosis of retinal disease and confirmed disease-causing variants in CEP78, CEP250, ARSG, or ABHD12. CEP78-related disease included sensorineural hearing loss (SNHL) in 6/7 patients and demonstrated a broad phenotypic spectrum including: vascular attenuation, pallor of the optic disc, intraretinal pigment, retinal pigment epithelium mottling, areas of mid-peripheral hypo-autofluorescence, outer retinal atrophy, mild pigmentary changes in the macula, foveal hypo-autofluorescence, and granularity of the ellipsoid zone. Nonsense and frameshift variants in CEP250 showed mild retinal disease with progressive, non-congenital SNHL. ARSG variants resulted in a characteristic pericentral pattern of hypo-autofluorescence with one patient reporting non-congenital SNHL. ABHD12-related disease showed rod-cone dystrophy with macular involvement, early and severe decreased best corrected visual acuity, and non-congenital SNHL ranging from unreported to severe. This study serves to expand the clinical phenotypes of atypical USH. Given the variable findings, atypical USH should be considered in patients with peripheral and macular retinal disease even without the typical RP phenotype especially when SNHL is noted. Additionally, genetic screening may be useful in patients who have clinical symptoms and retinal findings even in the absence of known SNHL given the variability of atypical USH

Where, When and Why Brain Activation Differs for Bilinguals and Monolinguals during Picture Naming and Reading Aloud

Using functional magnetic resonance imaging, we found that when bilinguals named pictures or read words aloud, in their native or nonnative language, activation was higher relative to monolinguals in 5 left hemisphere regions: dorsal precentral gyrus, pars triangularis, pars opercularis, superior temporal gyrus, and planum temporale. We further demonstrate that these areas are sensitive to increasing demands on speech production in monolinguals. This suggests that the advantage of being bilingual comes at the expense of increased work in brain areas that support monolingual word processing. By comparing the effect of bilingualism across a range of tasks, we argue that activation is higher in bilinguals compared with monolinguals because word retrieval is more demanding; articulation of each word is less rehearsed; and speech output needs careful monitoring to avoid errors when competition for word selection occurs between, as well as within, language

Does spatial locative comprehension predict landmark-based navigation?

In the present study we investigated the role of spatial locative comprehension in learning and retrieving pathways when landmarks were available and when they were absent in a sample of typically developing 6- to 11-year-old children. Our results show that the more proficient children are in understanding spatial locatives the more they are able to learn pathways, retrieve them after a delay and represent them on a map when landmarks are present in the environment. These findings suggest that spatial language is crucial when individuals rely on sequences of landmarks to drive their navigation towards a given goal but that it is not involved when navigational representations based on the geometrical shape of the environment or the coding of body movements are sufficient for memorizing and recalling short pathways

Haptic spatial configuration learning in deaf and hearing individuals

The present study investigated haptic spatial configuration learning in deaf individuals, hearing sign language interpreters and hearing controls. In three trials, participants had to match ten shapes haptically to the cut-outs in a board as fast as possible. Deaf and hearing sign language users outperformed the hearing controls. A similar difference was observed for a rotated version of the board. The groups did not differ, however, on a free relocation trial. Though a significant sign language experience advantage was observed, comparison to results from a previous study testing the same task in a group of blind individuals showed it to be smaller than the advantage observed for the blind group. These results are discussed in terms of how sign language experience and sensory deprivation benefit haptic spatial configuration processing

Gesture production patterns in aphasic discourse: in-depth description and preliminary predictions

Background: Gesture frequently accompanies speech in healthy speakers. For many individuals with aphasia, gestures are a target of speech-language pathology intervention, either as an alternative form of communication or as a facilitative device for language restoration. The patterns of gesture production for people with aphasia and the participant variables that predict these patterns remain unclear.Aims: We aimed to examine gesture production during conversational discourse in a large sample of individuals with aphasia. We used a detailed gesture coding system to determine patterns of gesture production associated with specific aphasia types and severities.Methods & Procedures: We analysed conversation samples from AphasiaBank, gathered from 46 people with post-stroke aphasia and 10 healthy matched controls all of whom had gestured at least once during a story re-tell task. Twelve gesture types were coded. Descriptive statistics were used to describe the patterns of gesture production. Possible significant differences in production patterns according to aphasia type and severity were examined with a series of analyses of variance (ANOVA) statistics, and multiple regression analysis was used to examine these potential predictors of gesture production patterns.Outcomes & Results: Individuals with aphasia gestured significantly more frequently than healthy controls. Aphasia type and severity impacted significantly on gesture type in specific identified patterns detailed here, especially on the production of meaning-laden gestures.Conclusions: These patterns suggest the opportunity for gestures as targets of aphasia therapy. Aphasia fluency accounted for a greater degree of data variability than aphasia severity or naming skills. More work is required to delineate predictive factors

Superior spatial touch:improved haptic orientation processing in deaf individuals

<p>The present study investigated haptic spatial orientation processing in deaf signers, hearing sign language interpreters, and hearing controls. Blindfolded participants had to set two bars parallel in the horizontal plane, with either a 2-s or a 10-s delay between inspection of the reference bar and the setting of the test bar. The deaf group outperformed the other two groups which did not differ from each other. Together these results indicate that deaf individuals can better identify the allocentric spatial coordinates of haptically inspected orientations. These results are discussed in terms of the possible neurocognitive consequences of auditory deprivation.</p>
